IMPROVEMENT IN GOVERNORS FOR STEAM-ENGINES.

Specification forming part of Letters Patent No. 196,236, dated October16, 1877; application filed September 3, 1877.

To all whom it may concern:

Be it known that we, JOSEPH KURTEN and LOUIS KRAMER, both of the city ofSt. {Louis and State of Missouri, have invented certain new and usefulImprovements in Governors for Steam-Engines, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawing, forming a part of this specification.

This is'an improvement in that class of governors having acounter-balance lever, tending to raise the valve-stem in opposition tothe centrifugal action of the rotating balls, the weight on said leverbeing adjustable, so as to. increase or diminish its influence on thestem.

Our improvement consists in supportingthe counter-balance weight at thelower end of a swinging rod, oscillating upon a standard, which isadjustably attached to the counterbalance lever. The purpose of thisconstruction is to make the action of the governor more sensitive by theautomatic outward movement of the ball when the lever descends, thusincreasing the influence of the lever upon the valvestem, and viceversa.

The drawing is a perspective view of a governor with our improvementapplied thereto. We claim no novelty in any part of the governor exceptin the devices for the support of the counter-balance weight upon thecounter-balance lever, and it will'be superfluous to give a generaldescription of the governor. It will be understood that the upwardmovement of the valve and valve-stem increases the size of thevalve-port, and that the centrifugal force of the balls B tends to forcedown the valve-stem A and decreases the area of the steam-ports. I

The coimter-balanee lever G has the usual pivotal collar-connection Dwith valve-stem. Said lever O is fulcrinned at c, and extends outwardfor the support of the coimter-balance weight E. This weight issupported upon the lower end of the pendulum-rod F, supported at theupper end upon the standard Gr, saidstandard being bowed outward at g toallow the ball or weight E free oscillation upon its pivot e, at the topof the standard. The foot y of the standard has a socket through whichpasses the lever O, the standard being adjustable endwise uponthe'lever, and being fixed in position thereupon by a set-screw, H,

or by other means.

The part of the lever\O passing through the socket may be angulai orprovided with a feather-key, to prevent the standard from turning on thelever.

The weight may be attached to the rod F as indicated in the drawing, orin any other suitable manner.

The operation of our improvement is as follows: The standardGis adjustedupon the lever so as to give the required mean speed to the engine. Onan increase of duty on the engine it will slow up, and the weighted endof the lever G will descend, giving more steam. The descent of the leverwill tiltoutward the top of the standard G, and this will cause theweight E to swing outward, increasing its in flnence on the lever, and,consequently, the sensitiveness of the governor is increased and itsaction accelerated. On a machine being stopped, so as to decrease theduty of the engine, the weight E moves inward, and the increased speedof the engineis at once checked, as the lever does not oppose thelifting of the rotary balls to the same extent. as it would if theweight E was fixed upon the lever.

We claim as our invention The combination, with lever O, of the standardG and hanging weight E F, for the purpose set forth.
